Abstract: 348,649. Tweezers. STICKEL, C. W. and TUTTLE, W. R., 77, South Avenue, Rochester, New York, U.S.A. Feb. 13, 1930, No. 4831. [Class 61 (ii).] Tweezers for removing superfluous hairs comprise a casing 10, a pair of jaws 14, Figs. 2 and 8, slidable in the casing, a spring 27 for moving the jaws backward, and a manually-releasable detent 28 for holding the jaws in a forward position in the casing. The jaws 14 are integral with a strip of spring metal bent at 13 to form parallel arms 11, 12, and are held in the retracted position by the spring 27 which is guided by a rod 23 attached to pins 21, 22 secured to the casing 10, and bears against the pin 21 and the end 13 of the arms 11, 12. The arm 11 is provided with a finger-piece 18 passing through a slot 20 in the casing, and the arm 12 is provided with the detent 28 which is adapted to engage the front end of the casing when the arms are moved forward. A closing-pin 31 and a releasing-pin 32 pass through the casing and bear respectively against the arms 11, 12. The jaws 14, Fig. 8, are tapered to a point 15 and are provided on the inner surface with a concavity 16 thus producing a gripping edge 17. A cap 37 is provided to cover the jaws 14. In use, the jaws are moved forward by the finger-piece 18, thus compressing the spring 27, until the detent 28 engages the front of the casing. The jaws are then placed astride the hair to be removed, the pin 31 pressed to close the jaws and the pin 32 simultaneously pressed to release the detent 28, when the spring 27 quickly retracts the jaws, thus removing the hair.

Title: Process for the manufacture of glue, gelatine or the like in the form of small balls or grains
IPC: C09H9/04
Filed: 1924-02-28
Abstract: 235,263. Akt.-Ges. fur Chemische Produkte vorm. H. Scheidemandel, Sakom, D., and Askenasy, P. Feb. 28, 1924. Spray, freezing.-Glue, gelatine or the like is obtained in small beads or grains by passing its solution in the form of drops through a cooling agent comprising a liquid miscible with the colloid, or a gas or gaseous mixture, or a liquid immiscible with the colloid, the colloid in the last case being subsequently passed through a cleansing liquid. As miscible cooling liquids water, aqueous solutions of salts, or aqueous emulsions may be used. In using a gaseous cooling agent, the drops of colloid may be caused to pass in countercurrent to the gas or they may be sprayed into a container in which the gas is held under pressure. Suitable immiscible cooling liquids are benzol, benzine, trichlorethylene, tetrachlorethane, carbon bisulphide, and benzyl alcohol, and suitable cleaning liquids for use in conjunction therewith are water, aqueous solutions of salts, and aqueous emulsions. The cooling liquid, if lighter than the cleansing liquid, may be superposed thereon, the specific gravity of the cleansing liquid being, if desired, increased by the addition of soluble substances; if the cooling liquid is the heavier, the grains are collected and passed through a lighter cooling liquid superposed on a cleansing liquid.

To prevent rotation of the discs one of the wires 15 is offset, Fig. 4, and engages a recess in each of the discs. To connect the end fittings to the core the ends of the wires are forced outwards against the walls of recesses 10 by conical members 9, molten metal being run into the recesses, if required. Pins 14 may assist in securing the end fittings to the rod. In modified constructions, sleeves areinterspaced with the discs and metal ferrules are provided along the length of the rod. If preferred, the central core may comprise a single rod having flattened ends by which it is secured to the end fittings.

Abstract: 972,817. Universal joints. DANA CORPORATION. Feb. 12, 1962 [March 6, 1961], No. 5387/62. Heading F2U. A constant velocity ratio universal joint which permits angular and axial movement between shafts 16, 30 comprises torque transmitting balls 58 in opposed arcuate or elliptic grooves 54, 56 formed in a sleeve 12 fast with the shaft 30 and the enlarged end 14 of the shaft 16, respectively, and pilot units 62 which coact with the balls 58, a smaller groove 60 and cam surfaces 64 in order to position the balls 58 in a plane which bisects the angle between the shafts 16, 30. As shown, the pilot units 62 are balls but may, Fig. 4 (not shown), be segments which slide in the smaller groove and have recesses which carry the ball 58 and cam surfaces which coact with the cam surfaces 64. The grooves 54, 56 may, as shown, be straight or may, Figs. 7 and 8 (not shown) be helical and produce an axial thrust between the shafts 16, 30 during operation. Since there is no mechanical contact between the sleeve assembly 12 and shaft end 14 the joint permits axial movement between the shafts 16, 30. A flexible cover 42 and seals 36 prevent lubricant escaping from and dirt entering the joint. Reference has been directed by the Comptroller to Specification 898,753.

Abstract: 2 - Amino - 1 - oxynaphthalene - S - sulphonamide-4-sulphonic acid is obtained from 1 : 8-naphthsultone by sulphonating, nitrating or nitrosating, treating with ammonia and then reducing; the treatment with ammonia may take place at any stage. According to examples (1) the sultone is sulphonated with fuming sulphuric acid, nitric acid added and the sodium salt of the 1 : 8-naphthsultone-2-nitro-4-sulphonic acid isolated by salting out; the sodium salt is treated with concentrated ammonia to form the 2-nitro-1-oxynaphthalene -8- sulphonamide - 4 - sulphonic acid which is then reduced with iron and sodium bisulphite; the reduction may precede the treatment with ammonia: (2) 1-oxynaphthalene-8-sulphonamide is sulphonated with concentrated sulphuric acid containing a little fuming acid at 10 DEG  C. and the sodium salt of the product salted out; the latter is converted to the 2-nitrosocompound by treating with sodium nitrite in acid solution, and reduced with iron and sulphuric acid at 30-40 DEG  C. p   Azo dyes and soluble metal compounds thereof.-The diazo compound of the above described 2-amino-1-oxynaphthalene-8-sulphonamide - 4 - sulphonic acid, when coupled with the usual components, yields mordant dyestuffs which may be converted into soluble metal compounds by treating with an agent yielding a metal such as a chromium or copper compound.  The products dye wool in orange, brown, red, blue, violet &c. shades and may also be used in printing.  In an example the diazo compound is coupled with b -naphthol and the dyestuff converted to the chromium compound by boiling with chromium fluoride. A table is given showing the properties of the dyestuffs, and of their chromium and copper compounds, derived from the diazo compound and the following components:-a -and b -naphthol, 5 : 8-dichlor-1-naphthol, 2 : 3-oxynaphthoic acid, 3-oxy-1 : 8-naphthalene-dicarboxylic acid, 1 : 4- and 2 : 6-naphthol sulphonic acids, b -resorcylic acid, resorcin, and 1-phenyl-3-methyl-5-pyrazolone and the 31-sulphamido-, 31-nitro-, and 41-oxy-31-carboxy-derivatives thereof.
